While the Williams sisters put on a show at night, these five interesting things happened during the day Monday at the Indian Wells Tennis Garden.

1. Fritz fights his way into Round of 16

Taylor Fritz, whose father Guy Fritz used to coach at College of the Desert, has reached new territory at the BNP Paribas Open. He pushed veteran Fernando Verdasco to a third-set tiebreaker and Fritz dominated it 7-1 to finish off a rousing 4-6, 6-2, 7-6 win on Stadium Court. When Fritz won the final point, he threw his racket down, whipped his Nike headband off and let out a colossal roar that may still be reverberating around the Tennis Garden. It was a big moment for him, clearly.

"Yeah. You know, just to get through that match was, you know, I got to let a lot of emotions out that I kept in," he said. "And to pull out a match whenever it's close like that can go either way. You're nervous. It just makes the feeling even better when you win and to have the crowd supporting, as well. It's just like -- it's like a dream."

He'll advance to face another unseeded player in Borna Coric of Croatia in the Round of 16.

American wild card Danielle Collins apparently hasn't heard that wild cards are supposed to be shuffled out of the draw quickly in a big tennis tournament. The 24-year-old American moved into the Round of 16, dispatching Sofya Zhuk 6-4, 6-4 on Monday. That sets up a date Tuesday with Carla Suarez Navarro for a trip to the quarterfinals.

"Yeah, I mean, luckily I had the experience last year playing this tournament," Collins said. "And, you know, it didn't go the way that I wanted it to. I kind of got crushed in the first round last year. And now, you know, I know what to expect. I'm more confident. I'm more familiar with the players. I'm just learning more and more, and I think that, you know, you can see that when I'm on the court."

We can see it, Danielle. We can see it.

3. So long, Sloane

U.S. Open champion Sloane Stephens was not able to keep the roll going for American women at this event. Stephens, the No. 13 seed, was dispatched by No. 20 Daria Kasatkina 6-4, 6-3 on Stadium Court. She wanted to win, of course, but she wasn't down for too long.

"Obviously not my best tennis today, but fortunately we get to play every single week. So, yeah, I mean, not going to be too down about it. There's always next week and the week after," Stephens said. "There's always going to be another opportunity, so just kind of look forward to that, and that's all I really take away from it."

4. Top 10 men: one up, one down

While the Williams sisters were toiling on Stadium Court, a pretty big upset took place on Stadium 2 as the No. 5-seeded man Dominic Thiem, one of the toughest possible opponents in Roger Federer's quarter of the draw, was taken down by Pablo Cuevas. Cuevas, who made a nice run here last year, won 3-6, 6-4, 6-2. Another top 10 man did survive. Kevin Anderson, the No. 7 seed who is playing his best tennis at age 31, beat Nicolas Kicker 7-6, 7-6.

5. Women's quarterfinals set

Tuesday may be the best day of tennis during the course of the BNP Paribas Open, because all 16 remaining women are in action, as well as half the remaining men's field. Let's take a look at the "Sweet 16" on the women's field and how they line up:
